Sampling, Analysis and Data Verification

Industry standard sampling methodology was used. RC samples were split and sampled at 1 m intervals using a three-tier riffle splitter. The resultant 2 kg samples were dispatched to the laboratory where they were crushed, dried and pulverised to produce a sub sample for analysis.

Diamond drill core was generally started at HQ size progressing to NQ in harder more competent rock. Core was generally oriented but not all. Sampling was generally at 1 m intervals with half sawn core sampled.

Three laboratories were used for gold assaying of Kiaka samples, including ALS Chemex (Ouagadougou and Johannesburg), BIGS Global (Ouaga) and SGS Ouagadougou. All laboratories utilised an aqua regia digest followed by fire assay with an AAS finish for gold analysis. Appropriate QA/QC procedures were undertaken throughout.

From 2024 onwards, GC samples have been assayed at SGS (Ouagadougou, AU_FAA505). Samples were dried, crushed and pulverised to produce a sub sample for analysis for gold by 50 g standard FA method followed by AAS finish with a detection limit of 0.01 g/t Au.
